vyos_command - Run one or more commands on VyOS devices
New in version 2.2.
Synopsis
- The command module allows running one or more commands on remote devices running VyOS. This module can also be introspected to validate key parameters before returning successfully. If the conditional statements are not met in the wait period, the task fails.
- Certain
show
commands in VyOS produce many lines of output and use a custom pager that can cause this module to hang. If the value of the environment variableANSIBLE_VYOS_TERMINAL_LENGTH
is not set, the default number of 10000 is used.
Options
parameter | required | default | choices | comments | |||||||||||||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
commands | yes | The ordered set of commands to execute on the remote device running VyOS. The output from the command execution is returned to the playbook. If the wait_for argument is provided, the module is not returned until the condition is satisfied or the number of retries has been exceeded. | |||||||||||||||||||||||||||||||||||||
interval | no | 1 | Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditions, the interval indicates how long to wait before trying the command again. | ||||||||||||||||||||||||||||||||||||
match | no | all |
| The match argument is used in conjunction with the wait_for argument to specify the match policy. Valid values are all or any . If the value is set to all then all conditionals in the wait_for must be satisfied. If the value is set to any then only one of the values must be satisfied. | |||||||||||||||||||||||||||||||||||
provider | no | A dict object containing connection details. |
|||||||||||||||||||||||||||||||||||||
| |||||||||||||||||||||||||||||||||||||||
retries | no | 10 | Specifies the number of retries a command should be tried before it is considered failed. The command is run on the target device every retry and evaluated against the wait_for conditionals. | ||||||||||||||||||||||||||||||||||||
wait_for | no | Specifies what to evaluate from the output of the command and what conditionals to apply. This argument will cause the task to wait for a particular conditional to be true before moving forward. If the conditional is not true by the configured retries, the task fails. See examples. aliases: waitfor |
Examples
tasks: - name: show configuration on ethernet devices eth0 and eth1 vyos_command: commands: - show interfaces ethernet {{ item }} with_items: - eth0 - eth1 - name: run multiple commands and check if version output contains specific version string vyos_command: commands: - show version - show hardware cpu wait_for: - "result[0] contains 'VyOS 1.1.7'"
Return Values
Common return values are documented here Return Values, the following are the fields unique to this module:
name | description | returned | type | sample |
---|---|---|---|---|
failed_conditions | The list of conditionals that have failed | failed | list | ['...', '...'] |
stdout | The set of responses from the commands | always apart from low level errors (such as action plugin) | list | ['...', '...'] |
stdout_lines | The value of stdout split into a list | always | list | [['...', '...'], ['...'], ['...']] |
warnings | The list of warnings (if any) generated by module based on arguments | always | list | ['...', '...'] |
Notes
Note
- Tested against VYOS 1.1.7
- Running
show system boot-messages all
will cause the module to hang since VyOS is using a custom pager setting to display the output of that command.
Status
This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
